On a 1986 Ford F-250 :
I believe " 39 " is a conventional axle ( non limited slip ) with ( 3.55 gearing )
I am not positive about this but, I believe that this indicates that the axle has a 3.00:1 gear ratio. Check with you local Ford dealer for a definitive answer.
I believe that is 3.50
Axle code? there are usually labels or tags on the axle with ratio and part numbers on them.Axle code? there are usually labels or tags on the axle with ratio and part numbers on them.
3.73 conventional axle ( non - limited slip )
I believe the axle code is listed on a sticker on the end of the drivers door The axle code will correspond to an axle ratio Once a person knows the axle code , the ratio can be looked up
No, I have a 3.55 in mine, I think there is one lower than that, and then a 3.73, and then a 4.10. What the hell is a 27? ---------------------------------------------------------------------- " OILMAN " had submitted a list of axle codes for the 1997 - 2004 F150 / F250 and the list shows axle code 27 as being a 3.31 conventional differential
On a 2003 Ford Explorer : Open the drivers door and there is an information sticker on the latch pillar You will find the axle code under " axle " Once you have the axle code you can determine the axle ratio
I believe axle code 19 is for a Ford conventional axle ( non limited slip ) with a 3.55 ratio
I was looking at the 1997 Ford F-250 Heavy Duty owners manual and there is a " C 5 " axle code listed 4.10 ratio - limited slip manufacturer - Ford capacity - 6,250 pounds
Open the drivers door and look for an information sticker , you are looking for the axle code . Submit a question with the axle code and I'll see if I can find the ratio axle code 86 axle tag s3708
3.31 ratio
Open the drivers door and look at the informaion sticker(s) for the axle code Each axle code corresponds to a specific axle ratio
